The worker, who was questioned by police days after the October slaying, was also named as a suspect in a similar strangulation last week.
That has prompted relatives of the first victim to ask why the worker, Anthony Triplett, was permitted to make house calls for Comcast while under investigation for the unsolved murder.
"I don't understand how he was allowed to keep doing cable jobs after he was questioned regarding my sister," said Loretta Shamley, the sister of Janice Ordidge.
Ordidge, 39, was found dead in the bathtub of her Hyde Park apartment Oct. 23.
Walsh said that Comcast officials were told in October that Triplett was a possible witness in the homicide investigation and had been questioned.
Triplett, 25, worked for Premier Cable Communications, which subcontracts for Comcast.It was not known how long he worked for the company. Premier officials could not be reached for comment.
